In the figure there is a $DC$ voltage regulator circuit, with a Zener breakdown voltage $= 6 V$ . If the unregulated input voltage varies between $10 V$ to $16 V$ , then what is the maximum Zener current?

Options:

Answer:

Solution:

$i_{1} = \frac{6}{4} = 1.5 mA$
Maximum current will be obtained for battery voltage

$16 V$
$i = \frac{16 - 6}{2} = 5 mA$
$i_{2} (\max) = 5 - 1.5 = 3.5 mA$
